workflow-release-prep — Local working tree → merge-ready PR

Degree of freedom: MIXED.

• Review & readiness (Phases 1–2): HIGH freedom — judge whether the change is coherent and safe.
• Git operations (Phases 0, 3–5): LOW freedom — commit / push / PR mechanics run exactly, in order. A wrong branch or a force-push is real damage.

Apply-now, end to end. Take everything in the local working tree — uncommitted + staged + untracked + unpushed commits, reviewed together as one release unit — and drive it to a merge-ready PR against main. Do not merge. This orchestrates existing skills rather than re-implementing them: hand deep passes to the specialists, own the sequence and the go/no-go.

Scope is the local working tree only — not open PRs, not merged-unreleased work. One developer's pending change, prepared properly.
